Shawn Oster has created a handy utility for Zune owners. Think that it's kind of strange that you can only use the mouse to play, pause, rewind, fast-forward, etc. with tracks in the Zune Desktop? Worry no more. Oster has you covered with his free utility, ZuneKeys, which adds keyboard shortcuts for the Zune Desktop. The utility takes up around 452KB of RAM and sits in the system tray and out of your way. Definitely worth a look.
